Answer to Question 1

B
Fluid needs per kilogram body weight during recovery decrease with age. This is because lean body mass decreases with age and is not affected by the type of metabolic stress.

Answer to Question 2

3
Rationale: Pre-operative fasting is not recommended in most cases and can result in diminished glucose stores post-operatively. Carbohydrate loading using orals liquids are being used to preserve glucose stores and reduce post-operative metabolic stress and insulin resistance. Fatigue and daily headaches are not common side effects of preoperative fasting.
